Piranha.core: Creating region object for a page fails

[iceHub82]

After creating a region object with a single property attached to my page like the following:

[PageType(Title = "Start page")]
[PageTypeRoute(Title = "Default", Route = "/start")]
public class StartPage : Page<StartPage>
{
        [Region]
        public Footer Footer { get; set; }
}

public class Footer
{
       [Field]
       public StringField FooterText{ get; set; }
}

And when the database table for _PostField is empty I can run the application and edit the FooterText, but as I soon as preview the page I get the following error:

An unhandled exception occurred while processing the request. ArgumentException: Object of type 'Piranha.Extend.Fields.StringField' cannot be converted to type 'Cms.Models.Regions.Footer'. System.RuntimeType.TryChangeType(object value, Binder binder, CultureInfo culture, bool needsSpecialCast)

The error makes sense as it saved as Piranha.Extend.Fields.StringField in the database. I guess it should be saved as Cms.Models.Regions.Footer.FooterText..

Am I missing something obvious?

Hi!

At the moment, a region cannot contain a single field.
So in your case, you could edit your StartPage to look like this:

[PageType(Title = "Start page")]
[PageTypeRoute(Title = "Default", Route = "/start")]
public class StartPage : Page<StartPage>
{
        [Region]
        public StringField Footer { get; set; }
}

More information about this can be find here under the Single Field Regions section.

So by adding another propertie the error will go away.. Alright it did the job and I can see it clearly now in the documentation.

Thanks!
